You didn't mention the author of the article this quotation came from
- "Stan Cox, a plant breeder and writer in Salina, Kansas. His book
Sick Planet: Corporate Food and Medicine will be published by Pluto
Press in Spring 2008".
The review referred to is available at
http://www.ehponline.org/members/2006/9149/9149.pdf not surprisingly
it doesn't quite say what was quoted. For example it didn't look at
studies investigating possible damage to DNA - DNA isn't even
mentioned within the report.
It also had a number of limitations
"Our study has several limitations. We restricted our analysis to
human laboratory studies. This resulted in a more homogenous set of
studies, but may have reduced the statistical power to demonstrate or
exclude smaller associations. The WHO has identified the need for
further studies of this type to clarify the effects of radiofrequency
exposure on neuroendocrine, neurologic, and immune systems (Foster
and Repacholi 2004). We considered including epidemiologic studies
but found that practically all of them were publicly funded. The
study’s primary outcome— the reporting of statistically significant
associations—is a crude measure that ignores the size of reported
effects."
You also didn't for example include the bit that said
"Although we have shown an association between sponsorship and
results, it remains unclear which type of funding leads to the most
accurate estimates of the effects of radiofrequency radiation. For
example, if researchers with an environmentalist agenda are more
likely to be funded by public agencies or charities, then their bias
may result in an overestimation of effects. Interestingly, studies
with mixed funding were of the highest quality."
Perhaps the fact the recent Essex Study was mixed funding influenced
you?
You also missed out "We stress that our ability to control for
potential confounding factors may have been hampered by the
incomplete reporting of relevant study characteristics."

Magda Havas is a botanist with a BSc in Ecology and an Associate
Professor (not Full Professor) at Trent University. She does not
appear to have published many scientific papers recently (and most in
the past have been within her primary field of botany and concerned
with acidification of lakes) but she is a regular contributor to
newspapers and speaker at the Toronto Dowsers Club. Her present
interest appears to be dirty electricity.
She has worked with an electrician, Graham-Stetzer who sells filters
supposedly eliminating this problem in buildings
http://www.stetzerelectric.com. Apparently fitting some of these
boxes altered blood sugar levels in diabetics, helped asthma
sufferers and allowed people with MS to walk again. Approximately 20
Graham-Stezter filters (apparently a capacitor in a box) would be
needed for an average home and they cost about $US30.00 each.
You can also buy a Graham-Stetzer Microsurge meter (Only US$100.00)
which plugs into the wall outlet and is claimed to measure the
“average magnitude of the changing voltage as a function of time
(dV/dt), which naturally emphasizes transients and other high
frequency phenomena that change rapidly with time. The measurements
of dV/dt read by the meter are defined as GS (Graham-Stetzer) units.
The G-S units are a measure of "harmful energy""
The British Columbia Centre for Disease Control evaluated the filter
and the results can be found via
